Great collectible for lovers of Hamms Beer! The Theo Hamm Brewing Company was founded in 1865 in St. Paul Minnesota. Hamm's was sold several times through its history to various companies including, Heublein in 1965, Olympia Brewing in 1975 and Pabst in 1983. Hamm's was purchased by Stroh Brewing in 1983 and operated the brewer until 1997. After over 137 years of operation, the plant closed its doors.

Miller Brewing later acquired the brand and now produces three Hamms beers.

Specimen stock certificates are certificates that were archived by printers and the company as perfect examples of the company’s stock issue. Specimen’s can be identified by their “specimen” stamp, stamped holes spelling “specimen”, or they are often issued with a serial number of a series of zeros. Often, they are also issued with no serial number at all. Specimens can also represent a design that was never issued. All of these attributes make the specimen stock certificate rarer than the issued version of the share. Many enthusiasts collect specimens as a whole new category of Scripophily.
